Cannot turn iommu on inside guest
So I want to turn iommu support on in a guest ( <type arch='x86_64' machine='pc-q35-4.1'>hvm</type>). Per [1] I tried to add to devices either <devices> <iommu model='intel'> <driver intremap='on'/> </iommu> </devices> or just a simpler <devices> <iommu model='intel /'> </devices>
